Ok, I'm using the VDSDLL right now, but for my purposes it's failing and I'd like to know if there's an API or any other way to get the color of a pixel at a specific location.

What I'm doing is taking in an image, loading it on my dialog and then using the VDSDLL to capture the color for each pixel in the image and then adding that color code to a list.

The problem is, the VDSDLL no longer returns the right colors after a few shots in a row. I don't think the dll considered someone repeatedly hitting it for this information a few thousand times in a row.

If there's any API, that would probably be more suited.. Any info appreciated and thanks in advance,
~Garrett

Can anyone convert this to VDS?

Gdi32.dll

Disregard. I found a forum post with the api call already converted. Smile

Well, vdscap.dll also gets the color of a pixel, just FYI.

vdscap, part of VDSDLL... read my first post in this thread. Wink

Besides, the api calls are quicker when called directly instead of via a dll.

What I was trying to do finally worked using the api calls, but yet, was a complete failure. I was converting images to html tables. worked great for like little 16x16 images, but the bigger they got, the longer it took a web browser to load.

I did this with one image that created a table with near 900,000 table cells.. LOL... Looked wonderful actually, just like the actual image, but it took like 5 minutes for google chrome to load the page.. LOL

in the end, it was a fun project that was successful and a failure. Smile

ah yes, so it is.

That is very cool. Care to share the api for the color selection? Smile

Oh great, now that I've deleted the file and forgot which post on the forums I found it! LOL.. No, I can find it again, hold on, BRB

BTW, the speed difference between using the dll and the api was extreme. Using the DLL for say a 16x16 image, if it didn't choke, took a few minutes while using the API it took less than a second.
